Patent GB-524895-A (GB)
Abstract: 524,895. Calculating-machines. MERCEDES BUROMASCHINEN-WERKE AKT. GES. Feb. 10, 1939, No. 4401. Convention date, Feb. 12. Addition to 496,720. [Class 106 (i)] In a machine with total-taking mechanism as described in the parent Specification wherein a cam shaft controls the operation of the typemembers by means of setting members mounted on a swingable frame, the swingable frame is adapted to be operated by a member which is positioned directly by unlocking a member of the total-taking mechanism and is actuated by means co-acting with the driving mechanism. When the total key 109 is depressed, cams 129, 131 are coupled to a rotary shaft 43 to effect total-taking as described in the parent Specification. As each denomination is cleared, a shaft 299 takes up an angular position representing the corresponding digit of the total, a corresponding one of a set of helically-disposed selecting fingers 325 thus being brought adjacent the end 340 of one of a set of levers 646 pivoted on a shaft 317, carried in a swinging frame 644, 645 pivoted about an axis 319a. As the cam 131 rotates a slide 179 descends and, by means of a projection 272, lowers a link 612, 613 so that its end 611 comes within the range of a lever 602 rocked by the cam 129. The link 612, 613 is thus moved to the left to rock a shaft 636 having arms 640, 641 which turn the swinging frame 644, 645 clockwise about its axis 319a. The lever 646 adjacent the operative selecting finger 325 is thus rocked anticlockwise,. whereby a link 652 pivoted to the lever 646 is pulled to the left to operate the corresponding type lever 81. The slide 179 is prevented from descending by known means when the totalizer is not in operative position so that the frame 644,. 645 is not then actuated by the rotary shaft 43 if the total key 109 is inadvertently depressed.

Abstract: 1375023 Anchor bolts HUYGMETAL NV 12 Nov 1971 [12 Nov 1970 27 Jan 1971] 52640/71 Heading F2H An anchor bolt assembly comprises a bolt having a substantially conical expansion head 3, and a brace 7 formed integrally from sheet metal. The brace 7 comprises two or, in a modification, three elongate portions 18 terminating in wings 5 which are curved so as to substantially encircle the head 3. Resilient hooks 27, 28 are formed at the free ends of the wings 5, the hooks 27, 28 engaging the surface of a hole 4 such that when the bolt is pulled in the direction P the wings 5 expand due to the relative movement of the head 3. Subsequent wedging of the assembly results at wing zones 31, the elongate portions playing no part in the wedging being countersunk in grooves 37. The resiliency of the wings 5 may be increased by transverse slits (Figs. 5 and 6, not shown). The wedging function of the wings 5 may be increased by folding under a portion of each wing 5 formed between two axial slots in each wing 5 (Fig. 8, not shown). The head 3 is strengthened by axial ribs 44, 45.

Abstract: 1388511 Valves; fluid pressure brakes WAGNER ELECTRIC CORP 15 Nov 1972 52679/72 Headings F2V and F2F A control valve 12 for use in a braking system comprises an inlet 34 for connection to a reservoir 10 of pressure fluid, filled from a service reservoir 7 through a check valve 15, and an outlet 35 through which the reservoir is normally connected to a spring-set portion 3 of a brake 4 to maintain that portion inoperative. The valve has a push-rod 37 which is normally pushed to the right from the position shown so that a piston 43 blanks an exhaust port 33. A control piston 47 carried by the push-rod is normally held in an ineffective position to the right of that shown by pressure applied to a control port 36 from the service reservoir 7 of pressure fluid, but if the pressure in that reservoir falls below a predetermined value, a spring 54 is able to move the control piston 47 to the left as shown, and with it, by virtue of an abutment ring 51, the push-rod 37. A closure member portion 46 is thus moved to connect the outlet 35 to the exhaust 33 instead of the inlet 34. Pressure thus falls in the line 11a to the spring-set portion 3 of the brake 4 which is thus operated. The brake may be temporarily disengaged by manually pushing in the push-rod 37 so as to reconnect the brake portion 3 with the reservoir 10, and, when service pressure has been restored, the system is re-set by pushing in the rod 37. In a system for a tractor-trailer combination, Fig. 4 (not shown), a relay valve (105) is interposed between the control valve outlet and the tractor brake and is supplied by a further reservoir (101) fed through a checkvalve (103) from the reservoir 6. The control valve outlet is also connected to a service reservoir (121) and a further reservoir (117), both on the trailer, and these are connected through relay valves (125, 115) to the service and spring- set portions (4a, 3a) of the trailer brake. A switching spool valve, Fig. 6 (not shown), controlled by the service pressure acting on a piston (222) on the end of the spool may be arranged normally to connect the service pressure to the inlet of the control valve 12 but, when the service pressure falls, to connect the reservoir 6 to that inlet.

IPC: G01S15/60
Filed: 1971-11-17
Abstract: 1415839 Acoustic Doppler systems DETECTRONIC Ltd 14 Nov 1972 53333/71 Heading H4D  The speed of a boat relative to water is measured by a CW acoustic Doppler system in which the extracted Doppler difference frequency is divided to give a first quotient frequency which is a predetermined function of the Doppler difference frequency per unit increment of boat speed, and the first quotient frequency is further divided by a constant divisor to give a signal for actuating a speed indicator. In the embodiment described the extracted Doppler frequency signal is converted to a train of pulses at the Doppler frequency and these are fed to a first frequency divider which is adjustable to give a predetermined output frequency change per unit speed change. This allows any offset of the acoustic beam direction from the boat travel direction to be taken into account. The divider output is applied via a second frequency divider, having a selectable division ratio, to a frequency-to-current converter driving a deflection-type speed indicator, and is applied via a fixed division ratio part of the second divider to a counter which logs distance travelled. The selectable ratio determines the range of speed indicated.

Abstract: 1372868 Modulating light F HOFFMANN-LA ROCHE & CO AG 18 Nov 1971 [4 Dec 1970 13 April 1971] 53678/71 Heading H4F The surfaces of plates 14, 15 bounding a liquid crystal layer 16 are prepared, e.g. by rubbing with a cotton plug, so that the immediately adjacent molecules of layer 11 are constrained to lie in a respective single direction parallel to the surface, the respective directions for the two plates being non-parallel, e.g. at 90 degrees, so that layer 16 possesses a helical structure extending between the plates and is optically active. As particularly described, layer 16 may be a pure nematic compound with positive dielectric anisotropy, and plates 14 and 15 are conductive SnO 2  coated glass plates. Application of an A.C. or D.C. electric field above a threshold voltage tends to destroy the helical structure and optical activity, Figs. 3 and 4 (not shown), as may be observed by placing the cell 11 between parallel or crossed polarizers 12, 13, since the molecule axes tend to align with the field. In modifications, (a) the layer 16 may additionally include a cholesteric compound, the mixture naturally tending to have a helical structure; only one plate surface needs preparation to fix the helical structure, (b) liquid crystal 16 may be coloured, (c) analyser 13 may be secured to a mirror for operation in a reflective mode. Different locations in the cell may be activated by X-Y addressing electrodes, for example for use as a write-in matrix for a hologram store (the coherence of the transmitted light being retained). Further references to uses of the shutter are to television, data processing, and in spectacles wherein the absorption is controlled by the incident light intensity.

Abstract: 1359239 Data processing system; error detection INTERNATIONAL BUSINESS MACHINES CORP 22 Nov 1972 [30 Dec 1971] 54048/72 Heading G4A A data processing system includes a central data processing unit (not shown), a peripheral unit control processor 1 having an internal store 2 and being arranged to execute error detection programs relating to errors in its associated peripheral units 3, an interface processing unit 4 having an internal store 5, and an external store 6 connected to the interface processor and arranged to store error detection programs, the arrangement being such that the interface processor 4 transfers a selected error program from the external store 6 to its internal store 5 and the control processor 1 transfers the error program from the interface processor store 5 to its internal store 2 for execution.  The arrangement allows error diagnosis of the peripherals to be performed independently of the central processing unit. During normal operation of the system the interface processor 4 is controlled by the central processor (CPU) via line 10. A special code is entered via keyboard 8 to inform the CPU that processor 4 is unavailable. A list of available error programs stored on tape 6, it being stated that a magnetic disc may be used, is read into processor 4 and displayed at 7. One of the programs is selected using the keyboard 8 and is read from store 6 into the internal store 5. The peripheral processor 1 is then informed that an error program has been selected. Processor 1, after executing each instruction originating from the CPU, checks whether an error program has been selected and, during periods when it is otherwise unoccupied, transfers the program into its internal store 2 for execution also during periods when it is otherwise unoccupied. Following execution of an error program any resulting data is transferred to processor 4 for display at 7. Further error programs may then be selected by the keyboard 8. Alternatively several error programs may be chained together, a subsequent program being selected by a program just finishing and being written into store 2 as above to replace the earlier program.
